Answer
$ t\leq -4$
The graph is shown below.
Work Step by Step
The given inequality is
$\Rightarrow 24\leq -6t$
Divide each side by $-6$. Reverse the inequality symbol.
$\Rightarrow \frac{24}{-6}\geq \frac{-6t}{-6}$
Simplify.
$\Rightarrow -4\geq t$
Hence, the solution is $ t\leq -4$.
Use a close circle because $-4$ is a solution.
Shade the number line on the left side.
